Embodiment Construction
[0014] The method for refining titanium tetrachloride by removing vanadium from aluminum powder of the present invention comprises the following steps:
[0015] ① The crude titanium tetrachloride test solution removes high-boiling impurities, and the generated impurities flow into the residue liquid container;
[0016] ② The crude titanium tetrachloride test solution removes low-boiling impurities, and the resulting distillate is further processed;
[0017] ③ Add aluminum powder and clear liquid to the crude titanium tetrachloride test liquid, remove vanadium and aluminum to obtain refined titanium tetrachloride, and the residue liquid enters the residue liquid container;
[0018] ④The residue liquid is settled to obtain a clear liquid and an underflow, the clear liquid is used for vanadium and aluminum removal, and the underflow can be further purified;
[0019] The method for removing vanadium and refining titanium tetrachloride from aluminum powder of the present invention...
